5. Set the Modem Connection: field to external if a modem is installed. Set the field to
none if no modem is installed. This field must be administered or alarms will be generated.
Note:
Note: The Modem Connection: field cannot be set to none if Alarm Origination is
activated.
6. Set the Data Bits: field to 8 (default).
7. Set the Parity: field to none (default).
8. For non-United States installations, set the remaining modem fields as shown in Table 29
.
9. Press Enter when the modem fields are properly administered.

Field Description
Modem
Connection
Default is none. Set to external if a modem is used.
Modem Name This field is 20 characters long and permits alphanumeric
characters to provide a unique qualifier for a given modem.
RTS/CTS
Enabled
Informs modem that communication with the data source UART
is driven with RTS/CTS flow control. The default 6-character
field name is &H1. Set the field name to \Q3 for Intel modems.
This field is not case-sensitive.
Asynchronous
Data Mode
Configures modem as an asynchronous device. This
8-character field name has a default value of &M0 (default). Set
the field to &M0&Q0 for Intel modems. This field is not
case-sensitive.
DTE Auto-Data
Speed
Adjusts the speed of the data source (DTE) UART to the
outgoing (modem-to-modem) data rate. At maximum, this speed
is 9600 baud. It is not desirable to have the serial data fill the
modem buffer faster than the outgoing data rate, since data
compression is disabled. The field name has a 6-character blank
default value. The Paradyne products use S90=1 to enable this
functionality while the Intel product uses \J1 to enable similar
functionality. This field is not case-sensitive.
Disable Data
Compression
Turns off the default data compression algorithms used by most
modems. The field has a blank field of 6 characters as default.
The AT commands that control this are supported by similar
commands; however, these commands do not operate in the
same manner. The Intel modems require H0%C0 to disable
V.42bis & MNP Class 5 data compression algorithms. The
Paradyne products only use %C0 to disable both algorithms.
This field is not case-sensitive.
